This invention relates to improvements in smoking pipes, the primary object of the-invention being to provide more eilicient and vpractical means for cooling and cleaning the smoke, before it reaches the mouth of the smoker, by condensing the vapor out of the smoke and trapping the condensate. J,

Another important object of the invention is to provide smoke condensing and coolingl means of the above indicatedcharacter which is .adaptable for easy and convenient installationbetween the bit and the bowl of an ordinary pipel without alteration to such pipe.

Another important object of the invention is to provide such improved smoke condensing and cooling means in a specially constructed pipe having a conventional external appearance and no substantial increase in weight and little increased manufacturing cost over that of ordinary smoking pipes.

Other important objects and advantageous features of the invention will be apparentufrom the following description and appended drawings, wherein, for purposes of illustration only, specific embodiments of the. invention are setforth in detail.

In the drawings: *f

. Figure 1 is a side elevation of one embodiment.

Figure 2 is a central vertical longitudinal section therethrough.

Figures 3 and 4 are transverse vertical sections taken on the lines 3-3 and 4-4, respectively, of Figure 2.

Figure 5 is a side elevation of another embodiment, partly in vertical longitudinal section, and, Figure 6 is an enlarged vertical longitudinal section taken through the smoke compressing tube. j

Referring in detail to the drawings, and first to Figures 1 through 4, thereof, showing an embodiment of the invention involving a smoke condensing and cooling device adapted for installation in an ordinary smoking pipe, the numeral 1 generally designates such device. shown in association with an ordinary `smoking pipe comprising the bowl section 8 and the stem section 9. The bowl section 8 has a smoke passage IIJ, leading from the bowl. II, and enlarged at its outer end as a socket I2 intowhich the plug I3 of the stem section 9 is ordinarily inserted, the stem section having a smoke 'passage I4 extending therethrough and a bit at one end thereof.

-The smoke condensing and cooling device, is removably connected to vthe bowl section 8 and s claims..` (o1. 1an- 195) connected for cleaning or for replacement by a device already cleaned, is preferably made of transparent material, such as plastic, so that a condition of contamination thereof is readily apparent to indicate desirability of a change or replacement.

The device 1 is in the form of a cylinder I5 of the same outside diameter as the meeting parts of the smoking pipe and has an axial tubular plug I6 on its forward end to replace the stem 'plug I3 in the socket I2 of the bowl section, with the forward end of the cylinder I5 abutting the adjacent end of the bowl section. The cylinder `I5 is formed with an axial bore I1 of substantiallythe same diameter as and opening through the rear end of the cylinder to receive the pipe stem plug I3. The bore I1 terminates in spaced relation to the forward end of the cylinder, as `indicated at I8. The rear end of the cylinder is chamfered and forms with the end of the stem section 9 a triangular cross section annular smoke cooling channel. indicated at I9, opening into the bore I1.

A relatively small cooled anddried smoke passage 20 extends forwardly in the upper wall of the cylinder I5 from the rear end thereof, Where it lconnects with the annular passage I9, to a point about two-thirds of the length of the cylinder forwardly from the rear end thereof. The forward end of the passage 20 has a sharply rearwardly and downwardly angulated terminal 2l opening into the top of the bore I1, substantially in vertical alignment with the rear end of the metallic smoke compressing tube 22. A small radial passage 28 in the stem section plug I3 connects the stem section smoke passage I4 with the upper part of the annular passage I9. The smoke compressing tube 22 comprises a forward portion 23 whose bore is the same in diameter as the bowl section smoke passage I0, and a rearward reduced diameter portion 24 connected to the rear end of the portion 23 by a rearwardly tapered portion 25, the portions 24 and 25 extending axially Within and spaced from the sidewalls of the cylinder bore I1. The diameter of the tube portion 24 is substantially less than that of the tube portion 23 in order to obtain an effect of compressing smoke drawn into the bore I1 from the pipe bowl I I and direct and impinge this compacted smoke against a convexity at the rear end of the bore I1, in the form of a metal button 26 having a shank plug 21 inserted in and closing the forward end of the pipe stem section passage I4.

vstem section .9, and. therefore can be readily dis- With the foregoing construction. the exertion of suction by the smoker through the stem section smoke passage I4 draws smoke from the bowl II through the bowl section smoke passage I0, into the compressing tube 22. As the smoke is drawn through the tube 22 it is compressed and jetted into the cylinder bore I'I in a whirling movement and impinged against the button 26, with the result that Vapor and other particles present in the smoke are condensed and fall to the bottom of the bore I1 and there Iremain while the thus cleaned and cooled smoke passes off at the top of the bore I'I, and is furwith and in an enlargement 29 of the smoke passage I0', the tube A22 having a collar or diametrical enlargement 30 tting against the enlargement 29 at the forward end of the bore Il. Otherwise the construction of the rst de,- scribed embodiment is present in the embodiment shown in Figures 5 and 6, as indicated by similar but primed numerals.
